The term 'molecular scissors' refers to

A

recombinant DNA

B

restriction enzymes

C

Taq polymerase

D

polindromic nucleotide sequences.

Text Solution

Verified by Experts

The correct Answer is:
B

The restriction endonuclease enzyme inspects the length of a DNA sequence. Once it recongnises specific sequence, it binds to the DNA and cuts each of the two strands of the double helix at specific points in their sugar phosphate back bone. Special sequence in the DNA recongnised by restriction endonuclease is called palindromic nucleotide sequence. Restriction endonuclease enzymes are also known as molecular scissors or biological scissors or chemical knives or chemical scalpels.
